On one of our trips, (Honolulu, I think) there was a business which had vans that would meet you at the airport outside baggage claim and store your luggage in the van. Then when you were finished sightseeing, you called the driver to arrange a meeting place at the airport to pick up your bags and head back into the airport for departure. I was a little leery of this arrangement, but several Trip Advisor folks had used it and gave it a thumbs up, so we tried it and it worked great. I've often wondered if something like that would work at DIA.
Your industrial-style loft melds hardwood floors, exposed duct work, and stainless steel appliances beautifully, but the struggle is creating a cohesive design with your decor. Mix new and old, cold metal and warm woods to fit this style, and start with a signature piece, such as used school lockers. These lockers are industrial in nature, and whether the metal is flawlessly finished in a bright color or boasts naturally-occurring rust from years of neglect, they fit in with this design style. Used school lockers also offer a functional storage space in various sizes, with lockers as small as 12 inches by 12 inches, and as large as 30 inches by 66 inches. Once you decide on your lockers, keep your storage solution as functional as possible with a school locker organizer to make the most of the space with hanging shelves or small magnetic holders. School locker magnets can be that extra little space you need to hold pens, business cards, reminder lists, and other small items. Finding the right design pieces for your industrial-style loft can be somewhat difficult, but the sellers on eBay have you covered with a large selection of vintage items like school lockers.
Locking options: various types of key locking or padlocking facility are available now. Key locking options include flush locks, cam locks, or locks incorporated into a rotating handle; padlocking facilities may be a simple hasp and staple, or else a padlocking hole may be included in a handle, often called a latchlock. More modern designs include keyless operation, either by coin deposit (which may or may not be returned when use of the locker terminates), or by using electronic keypads to enter passwords for later reopening the locker. Some older lockers used a drop-latch which was incorporated into the door handle, and slid up and down and could be padlocked at the bottom in the "down" position, but these are less used now. Three-point locking is not possible with this type of latch, because it needs to be operated by means of a latch that rotates rather than slides up and down; so this drop-latch is probably a less secure locking option, which may be why it is little used nowadays. Prefect Combination locks are very popular in school lockers used in the UK due to their ease of use and the time and cost saved in the removal of locker keys.
